Q: My horn stopped working. Is it really necessary to have this fixed? Is there something I can check?
A: The horn is a safety device and should be fixed on your vehicle. Look in your owner’s manual to locate the fuse for this electrical circuit. If the fuse is not the problem, the electrical connections on the horn should be checked. You should also use a test light to see if you have 12 volts of power at the horn when the horn button is pressed. If you have power, then you have a bad horn. If you don’t have any power at the horn then the horn relay, bad horn switch, or a broken or corroded wire may be the culprit. Since some horn buttons are integrated with the air bags, I would leave disassembling the steering wheel for the professionals.
